Demo doesn't work

I treid to install the default DemoSolution.wsp that comes with SharePointInstaller. It claims to have installed correctly, but I can't find it anywhere to activate it. All I see is that directory C:\Program Files\Common Files\Microsoft Shared\web server
extensions\12\TEMPLATE\FEATURES\MondosoftDemoFeature\ was created.

Is there something wrong with the demo?

Where is the documentation for RequireDeploymentToCentralAdminWebApplication?
